November 29 Olga weakened to tropical storm status. With the thunderstorms rapidly diminishing, the storm weakened quickly, and Olga deteriorated further to a tropical depression on
November 30. Forecasters anticipated continued weakening until dissipation, although the cyclone was expected to move over an area of more favorable conditions, including warmer waters and lighter shear. Still existing as a tropical cyclone on December 1, Olga extended the hurricane season beyond its typical boundaries. It continued producing a small area of deep convection, prompting one forecaster to note that "Olga is stubbornly holding on to tropical cyclone status... for now." After reaching a position about 240 mi (390 km) northeast of the

although convection was weak, Olga was able to intensify further to winds of 45 mph (72 km/h). At the time, there was uncertainty whether the storm would strengthen further, possibly to near hurricane status, or rapidly weaken. Ultimately, an approaching trough caused weakening by increasing wind shear, while also forcing the storm eastward. On
December 4, Olga again weakened to a tropical depression as it lost most of its convection. Later that day, the circulation turned to the southeast as a ridge built to its north, and Olga degenerated into a remnant low pressure area, about 690 mi (1,110 km) east of

November 28, after finishing the second loop, Olga turned to the southwest due to a building ridge to its northwest. Around the same time, it began a steady weakening trend, due to strong wind shear displacing the convection. The eye became poorly defined as the center became exposed, and on

November 25, the storm began acquiring more characteristics of a tropical storm, such as detaching from the larger storm and developing more distinct convective rainbands. This was due to decreasing wind shear and continued atmospheric instability, although only marginally warm
